CANVAS LAYING AND CREASING MACHINE FOR INSOLES.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Application filed January 18, 1911. Serial No. 603,283.

making soles and particularly to such machines provided with means for laying and creasing reinforcing fabric which has been roughly applied to the soles.-

In making reinforced soles the operations 1 on the reinforcing fabric include a preliminary forming-in or setting of the fabric in the angle at the inner side of the rib, and in some cases a later beading of the fabric about the rib. The machine embodying the invention will be described as performing the formin -in operation, and will be illustrated as operating on what is known commercially as a Gem insole, on which the later beading operation is carried out, but itshould be understood that the invention is not limited to making Gem insoles as it is equally useful in making Economy insoles, or any other type of sole to be reinforced wherein the reinforcing fabric is to be secured at the inner side of a marginal lip or rib.

' The object of the present invention is to provide a simple machine for applying reinforcing fabric to ribbed soles, and especially for creasing or forming-in the fabric in the angle inside of the lip.

In accordance with this object one feature of the invention contemplates a construction which will hold a sole of a shoe on a table, means being provided for rotating the table and means being also provided for 00- acting with the table for creasing a layer of canvas to be used on the ribbed face of the sole, the said sole'being held in place on the table by. novel means which prevents upward movement of the sole with relation to the table or displacement thereof with relation to the tool used in the operation of creasing the canvas layer.

A still further feature of the invention contemplates the provision of novel means for driving the creasing implement and the sole retaining mechanism simultaneously with the table thereby guarding against the formation of folds in the canvas layer or damaging the material being treated.

W1th the foregoing and other objects in View, the invention consists in the features of construction and in the arrangement and combination of parts hereinafter more fully set forth and claimed.

In describing the invention in detail, ref

'erence will be had to the accompanying drawings illustrating the preferred embodiment of the invention, wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view, in elevation, of a machine embodying'the invention;

Fig. 2 illustrates a detail view of the tools of the machine, with a sole in operative pos1tion; v v

Fig. 3 illustrates a perspective view ofthe canvas supporting guard;

Fig. 4 illustrates a plan view of the sole with the canvas applied; and

Fig. 5 illustrates a sectional view of the sole on the line AB of Fig. 4.

In the embodiment of the invention illus trated in the drawings 6 denotes a base, 7 a standard having a bearing 8 thereon in which the power shaft 9 is rotatable, the base 6 also supporting a bearing 10 in which the forward end of said shaft 9 is journaled.

The power wheel 11, on the shaft 9, is driven in any appropriate way and a gear wheel 12 is also mountedon the shaft 9 and meshes with a gear wheel 13 on a shaft 14, which shaft 14 also carries a pulley 15 and a second gear wheel 16. I

An arm 17 has one end supported by the standard 7 to which it is connected by a pivot 18 and a bearing 19 is formed on the arm in which the shaft 14 is journaled. The arm 17 has an extension 20, forming the journal bearing for a shaft 21 carrying an idler 22. A belt 23 is run over the idler 22 and over the pulley 15 for the purpose of driving a shaft 24 through the medium of the pulley 25 which is mounted thereon. The shaft 24 is journaled in a sleeve 26 pivoted on a bracket 27 which is adjustably mounted through a medium of the slot 28 and cooperating set screw 29, on the forward end of the arm 17.

The shaft 24 carries on itslower end a canvas creasing tool 30 which is yieldingly held in a sleeve 26 by means of the spring 31 which encircles the shank of the tool 30 The sleeve is mounted on a pivot 32 in the bracket 27 and can be moved about said lation to the table.

pivot for the purpose of changing the angle of inclination of the tool 30 with relation to the Work table 33 which is rotatable in a standard 34 rising from the base 6. The angle of inclination is determined by ad justment of a set screw 2 carried by the bracket 27 and bearing against the sleeve 26.

The under surface of the table has a bev eled gear wheel 35 meshing with a gear Wheel 36 011 the shaft 9 and, therefore, the table is rotated under the influence of the shaft 9 to feed the sole. The arm 17 has a spring 37 connected to it, the said spring being also attached to the base 6, for automatically adjusting the said arm 17 withre- The arm 17 is furthermore provided with a link 38 which is con nected to a lever 39 pivoted on the journal bearing 10 and having an operating rod 40 by which the said lever is oscillated for moving the arm 17 away from the table against the action of the spring 37.

A shaft 41 is journaled in, a downwardly extending portion of the arm 17 and has a beveled gear wheel 42 thereon which meshes with a beveled gear wheel 43 mounted on a shaft 44 which shaft is journaled in a bear-. ing 45 formed on a forward extension of the arm 17. The shaft 41 is driven by a gear wheel 41 which meshes with the gear wheel 16. The end of the shaft 44 remote from the gear Wheel 43 is provided with a work engaging disk 46 which coacts with the table for the purpose of feeding the sole 47 past the tool 30 and withthe tool 30 for tightening the canvas against the lip or rib of the SQ-le.

A guard 48 is pivotally connected to the arm 17 and extends over the disk 46 and partially over the table 88 and is designed to coiiperate with the tools for the purpose of supporting the free margin of the reinforcing material while under treatment so that the same shall not contact with the retating presser. As shown in Fig. 3, the guard 48 has apertured cars 49 by which it is connected to the arm 17 In practice, a sole such as is shown at 47, which has been fitted as shown in cross section in Fig. 5, and had the canvas 48 roughly applied thereto is placed on the tahis 33 under the tools 30 and 46 which are raised from the table by lifting the arm 17.

Owing to the rotation of the table, and the rotation of the disk which co-acts with the table, the sole is moved with relation to the tool which, being rotated at an angle with relation to the table, acts on the canvas layer which has been roughly applied to the sole and creases it or forms it in, at the inside angle of the lip.

It has been found in practice that a machine embodying this invention is efiicient in pressing the canvas closer against the surface of the sole of the shoe, at the same time creasing the said canvas and causing it to adhere to the said sole.
